The thermal radiation has an effect on their thermal insulation performance when using silica aerogel composites at a high temperature. The effect of thermal radiation on the thermal conductivity of aerogel composites was investigated at different pressures and temperatures to regulate the gas phase heat transfer factors. The results show that the thermal conductivity of aerogel composites is decreased by 34% when the pressure is decreased from 100 kPa to 100 Pa under a weak radiant effect of 100 ℃, while the thermal conductivity is decreased by only 3% at 900 ℃ due to the thermal radiation effect. The effect of thermal radiation on the back surface temperature of aerogel composites was also investigated by a heat transfer model at different back surface temperatures. It is indicated that when the radiation heat transfer condition increases from 37 ℃ to 535℃, the temperature increase of the back of material model increases from 0 ℃ to 178 ℃ after removing the radiation heat transfer load between the back of the material model and environment. The temperature increase of the back of material model increases from 10 ℃ to 65 ℃ after removing the convection heat transfer load.

二氧化硅气凝胶复合材料在高温条件下使用时需要特别关注辐射传热对其隔热性能的影响。在100 ℃和900 ℃建立不同气体压力环境来调节气相传热因素以研究辐射传热对气凝胶复合材料热导率的影响。结果表明:在100 ℃弱的辐射传热条件下,气体压力由100 000 Pa降低到100 Pa,气凝胶复合材料热导率降低34%,而由于900 ℃强的辐射传热效应,当气体压力由100 000 Pa降低到100 Pa,气凝胶复合材料热导率仅降低3%。建立不同背面温度的传热模型以研究辐射传热对气凝胶复合材料背面温度的影响。结果显示,辐射传热条件由背面温度37 ℃增大到535 ℃,移除背面辐射传热载荷后材料模型背面温度的升高值由0 ℃增大为178 ℃,而移除对流传热载荷后材料模型背面温度的升高值由10 ℃增大为65 ℃。

二氧化硅气凝胶复合材料在高温条件下使用时需要特别关注辐射传热对其隔热性能的影响。在100 ℃和900 ℃建立不同气体压力环境来调节气相传热因素以研究辐射传热对气凝胶复合材料热导率的影响。结果表明:在100 ℃弱的辐射传热条件下,气体压力由100 000 Pa降低到100 Pa,气凝胶复合材料热导率降低34%,而由于900 ℃强的辐射传热效应,当气体压力由100 000 Pa降低到100 Pa,气凝胶复合材料热导率仅降低3%。建立不同背面温度的传热模型以研究辐射传热对气凝胶复合材料背面温度的影响。结果显示,辐射传热条件由背面温度37 ℃增大到535 ℃,移除背面辐射传热载荷后材料模型背面温度的升高值由0 ℃增大为178 ℃,而移除对流传热载荷后材料模型背面温度的升高值由10 ℃增大为65 ℃。

The thermal radiation has an effect on their thermal insulation performance when using silica aerogel composites at a high temperature. The effect of thermal radiation on the thermal conductivity of aerogel composites was investigated at different pressures and temperatures to regulate the gas phase heat transfer factors. The results show that the thermal conductivity of aerogel composites is decreased by 34% when the pressure is decreased from 100 kPa to 100 Pa under a weak radiant effect of 100 ℃, while the thermal conductivity is decreased by only 3% at 900 ℃ due to the thermal radiation effect. The effect of thermal radiation on the back surface temperature of aerogel composites was also investigated by a heat transfer model at different back surface temperatures. It is indicated that when the radiation heat transfer condition increases from 37 ℃ to 535℃, the temperature increase of the back of material model increases from 0 ℃ to 178 ℃ after removing the radiation heat transfer load between the back of the material model and environment. The temperature increase of the back of material model increases from 10 ℃ to 65 ℃ after removing the convection heat transfer load.
